One-piece bathing suits

The Sidestroke

Summersalt's insanely popular swimsuits are universally flattering on most body types and all ages and sizes, including styles for long torsos and maternity swimwear.

The brand's one-shouldered Sidestroke design is a best-seller (it sold out 25 times within its first year of sale!) and for good reason — 5 million body measurements were taken from 10,000 women to inform the fit, which users say feels soft and compressive without being too tight. While it's not cheap, reviewers call it "the best investment" and say it's "worth every penny." The style, which has no cups or padding, is available in 11 colors and patterns, including colorblock options and a range of solid neutrals and brighter hues. This suit is also available in a bikini version.

Sizes: 0-24

High Neck One-Piece

The bathing suits from the best-selling Amazon brand Tempt Me are fashionable, flattering and affordable. The brand offers a wide range of trendy styles and prints to pick from, but this high neck one-piece is its most popular, with over 32K reviews on Amazon.

While GH staffers who own this machine-washable swimsuit say it might not be the absolute best quality bathing suit out there, you do get a good amount of bang for your buck (one editor has been wearing this suit for years with only minor wear and tear). Plus, the mesh cutout, plunging back and high neck all work to make you feel sophisticated and sexy — and it's available in nearly 40 colors and patterns.

Sizes: XXS-26 Plus

Oceanus One-Piece Swimsuit

Miraclesuit's swimwear works like shapewear to flatter tummies, waists and hips. This style aced the Good Housekeeping Institute's slimming swimsuit tests, with the durable fabric standing up to elements like seawater, chlorine, sweat, UV rays and more, while our panel of reviewers rated it better than other tummy control swimsuits they've tried.

The sweetheart necklace and built-in underwire accentuates and lifts the bust while the mesh cutouts highlight curves in all the right places. Just note that while this style comes in a variety of colors and prints, it does have a limited size range (though there are plus-size and DD-DDD cup versions available).

Sizes: 8-18; 16W-24W

V-Neck One-Piece

Available in two dozen different shades and patterns, we're impressed with Cupshe's flattering styles and compressive materials designed to feel comfy during long beach and pool days.

A deep V-neck and side ruching are simple details that elevate this spaghetti-strap suit that features a front panel designed to be tummy-flattering. One five-star reviewer writes that she recommends this style to anyone who wants a comfortable, well-made swimsuit: "I especially recommend for anyone like me who just had baby and is trying to look stylish postpartum!"

Sizes: XS-XL

Ruched Bandeau One-Piece

Available in almost every color of the rainbow plus classic summer patterns like gingham and stripes, this one-piece bathing suit has hundreds of rave online reviews — and we can see why.

A full coverage bottom plus gentle ruching make it a comfortable yet stylish pick for all ages. Plus, the strapless top means no tan lines (it does come with removable straps though, FYI). One reviewer wrote that she owns four versions of this suit in different colors: " It's classy and slimming and so comfortable while carrying kids at the pool or beach. Great quality and design."

Sizes: 0-24

Cross Back One-Piece

Slip on this elegant one-piece and stroll onto the sand or pool deck in style. "I tried on about 40 swimsuits in a single day at the mall and this was the only one that was comfortable and flattering," writes one happy five-star reviewer. Figure-sculpting banding around the torso and crisscross straps in the back are cool without trying too hard.

Sizes: 2-16

SlenderSuit Wrap One-Piece

In GH Institute swimsuit tests, we found Lands' End swimsuits to be very durable, with fabric that was colorfast and held up to repeated laundering. Our testers also rated it as "most flattering": The brand's SlenderSuit is ideal for anyone looking for slimming details (thanks to a criss-cross design around the tummy area and compressive fabric). In addition to regular sizing, this style is also available in D, DD and DDD cup sizes, with petite, tall and plus options as well.

Sizes: 6-18 (regular/long); 4-18 (petite); 16W-24W (plus)

Leakproof Classic One-Piece Swimsuit

When it comes to the best period swimwear, Knix's pieces consistently outperform competitors in our tests, with its built-in liners absorbing up to three tampons of menstrual flow for protection even on heavy days. In addition to the high-level of absorbancy, our testers appreciated the flattering cut of this one-piece bathing suit featuring a built-in bra and adjustable straps; the fit is particularly ideal for larger busts with sizing up to a G cup. Just note Knix's suits are only available in black.

Sizes: XS-XXXXL+

Women's One-Piece

This budget-friendly bathing suit brand is the way to go if you need to own multiple suits. It's super popular on Amazon with thousands five-star reviews from users who say they wear it for swimming laps. With over 30 patterns and colors to choose from, the style features wide racerback straps for a good range of motion and a built-in bra.

Sizes: 2/4-14/16

Women's ProLT One-Piece Swimsuit

Whether you're a competitive swimmer or just prefer swimming laps to running on the treadmill, you're going to need a suit that's functional and won't get in the way of your workout.

Speedo is a favorite among professional athletes, and its one-piece styles are designed for performance so you can slip easily through the water. This best-seller may be basic in design but it'll stay put as you swim. Plus, the ProLT is made with durable fabric that the brand claims is chlorine-, sand- and sunscreen-resistant. Just note these suits run on the small side.

Sizes: 20-40

Plus-Size Sarong Front One-Piece

Swimsuits for All offers stylish, size-inclusive pieces for under $75. With sizes up to 34, this best-selling one-piece has a flattering mesh lining and a draped sarong-like front panel. With 15 colors and patterns available, one five-star reviewer on Amazon says: "Swimsuit construction is fantastic — solid fit for busty girls." Just note that the straps are not adjustable.

Sizes: 8-34

Lacey

Ta3 has a dozen swimsuit styles on their website, but the Lacey is one of the brand's most popular picks. Available in seven colors as well as regular/long and short lengths, the suit is made from a compression fabric akin to that of a sports bra. Peep the back and you'll see where the bathing suit gets its name. One online reviewer notes: "This suit is beyond expectations. I got the red in small and I’m just saying ... be ready to look like a Baywatch babe when you get it!"

Sizes: XS-XXXL

Clasp Halter Dress

If you prefer a style that offers even more coverage than a traditional one-piece, L.L.Bean has an assortment of swim shirts, shorts, dresses and skirts made of swimsuit materials that you can wear on the beach and in the water.

This halter swim dress in particular is a great option, offering various torso lengths, cup sizes and plus sizes. Numerous reviewers note how great it looks on, too, with one writing: "I like the extra cover that the skirt gives and [it] is flattering around my hips and thighs. It is a great look for women with hourglass figures."

Sizes: 8-26W

The Veronica One-Piece

Sure, this swimsuit is an investment, but reviewers say they love the Veronica for its "beautiful shape" and "flattering" fit. The structured and supportive top, featuring underwire cups and adjustable straps, is simple yet stylish, meaning this number can double as a bodysuit, too — pair it with jeans or a skirt for a night out while on vacation.

Sizes: XS-XL

The Mykonos

Popular amongst fashion bloggers, Andie's designs are minimalistic, with solid colors only and no embellishments or ruffles. There is a big focus on getting the right fit though: You're encouraged to take a fit quiz on the brand's website and all orders feature free shipping and returns so you can try on multiple styles at home.

Customers can't stop raving about the sleek lines of the Mykonos one-piece which is available in six colors and smooth or ribbed options. With hundreds of reviews, the swimsuit has a 4.7-star rating, with one reviewer calling it a "magic suit." It also comes in a long torso version, which is ideal if you're tall or have a torso on the longer side.

Sizes: XS-XXXL

Rumba One-Piece

The cut-0ut trend is still going strong, and this one-shoulder number is sexy but subtle thanks to its minimalist color palette. The horizontal and diagonal stripes combine with a side cut-out for a totally unique look that no one else will be wearing on the beach or by the pool.

Sizes: XXS-XL

Printed Recycled Swimsuit

Pull on this one-piece and immediately exude "quiet luxury" thanks to an abstract pattern that is actually Totême's monogram. We love the low-cut back and high-cut legs for medium coverage. Although there are only two colorways available and this suit is pricey at just under $200, the splurge may be worth it if you have the budget and value swimsuits made with recycled materials (the brand claims the fabric is made from 73% recycled fibers that have been diverted from landfills and oceans).

Sizes: XXS-XL

Genevieve Side-Tie One-Piece Swimsuit

For a less revealing look, Hermoza offers comfortable styles that are on trend but not skimpy. This suit's high neckline provides more built-in sun protection while the halter style gives it a sophisticated edge. The side sash adds a chic touch while simultaneously flattering your waist — no need for a tummy control panel.

Sizes: 2-14

Pique Shaping Plunge One-Piece

For those who like to stick to one classic suit to wear throughout the summer season, consider investing in Spanx's shaping one-piece. Like the brand's famous shapewear line, its swimwear line features flexible double-layer fabric and compressive mesh for a seamless fit that holds everything in place. The subtle plunge neckline, bust darts and cheeky rear coverage are sexy without being overtly so.

Sizes: XS-XXXL

Waterside V-Neck One-Piece

Specifically designed for swimming, this plunging one-piece is made for, well, plunging. A low-back and high side-cuts plus super soft, lightweight fabric allow you cut through water seamlessly. Plus, you can adjust the straps and remove the cups if desired. Available in three neutral colors, reviewers say this one-piece is "flattering" and "well-made" but also note that it may not be the best choice for those with larger busts or butts.

Sizes: 2-14

Two-piece bathing suits

Ribbed Bikini

Our GH Institute textiles analysts are consistently impressed by the wide range of affordable and cute bathing suits from Aerie, and this ribbed bikini set is a favorite. Similar to the brand's top-selling crossover flare leggings, the crossover high cut cheeky bikini bottoms are super-flattering and compressive without being uncomfortable. The matching scoop bikini top, which is sold separately, is also a crowd-pleaser according to hundreds of online customer reviews.

Aerie often has sales, which can make buying both a bikini top and matching bottom equivalent to buying just one of those pieces at full price. Just note that you may have to sign up to be notified about certain sizes coming back in stock (we recommend shopping as early as possible in the summer season!).

Sizes: XXS-XXL

Retro Halter Ruched High Waist Bikini

With almost 21K reviews on Amazon, this two-piece is a bona fide best-seller at a great price. The adjustable halter top features structured cups with push-up lift while the ruched bottoms offer comfortable tummy control according to reviewers who call this suit "flattering" with "great support." We're also impressed with the range of sizes and colors available.

Sizes: XXS-XXL; 18-22 (plus)

Plunging Halter Bikini

Bikinis can be difficult to fit into if you have a larger bust as they often lack the proper support. Freya, a lingerie brand for larger cup sizes that's a top performer in our bra tests, gives you the support without having to sacrifice fashion for function. The brand's bikini tops feature lining and underwire and come in US cup sizes B-G.

We love the design of this plunging halter bikini top in particular — pair it with the matching high-waist bikini briefs for ample coverage.

Sizes: 28D-38G and XS-XL

The Scoop Bikini

If you're looking for support, where better to turn than a size-inclusive lingerie brand? After testing, Cuup's bras made our list of the best bra brands, and you'll find the same precision fit and supportive structure in its swimwear collection.

We appreciate that Cuup bikini tops have both band and cup sizing, so it’s easier to find your best fit, especially if you have a large bust. One GH editor says she also loves the Scoop bikini's "lightly compressive and supportive fabric and timeless, flattering silhouette." We recommend pairing the Scoop top with Cuup's matching highwaist bikini bottoms for comfortable coverage.

Sizes: 30-44, A-H (top); XS-XXXL (bottom)

High Waist Bikini Set With Tassel Trim

For those simply looking for something flirty and fun, Cocoship's swimsuits feature unique designs, with lots of tassels, ruffles and other embellishments including fun patterns like gingham and florals. This two-piece has close to 5K online customer reviews and a 4.4-star rating on Amazon. One satisfied customer writes, "This bathing suit is cute! I love the thickness of the fabric. I especially like the details are also in the back of the suit too."

Sizes: 4-16

Conscious Crop Bikini Top

From workout leggings to sports bras, Athleta is consistently a top performer in our exercise clothing tests. That's why we recommend its swimwear line to anyone partaking in vigorous water activities like paddleboarding or water skiing. We love this top-rated crop bikini top and its matching high-waist swim bottoms (sold separately) which are good-looking, comfortable and supportive.

Sizes: XXS-XL

V-Neck Tankini and High-Waisted Bottoms

Old Navy's tankinis are a customer favorite, with adjustable straps for comfort and a V-neck and fitted design for a touch of sex appeal. Reviewers say they appreciate the removable cups, though they do not they don't love the darted bust quite as much. Pair the top with the matching high-waisted cross-front bikini bottoms (sold separately). Plus, if you're familiar with Old Navy's famous summer flip-flop sales, know that the brand's bathing suit sales run just as deep, adding discounts on top of already budget-minded price tags.

Sizes: XS-4X

Women's Ruffle Halter Tankini Set

What a deal: For under $35, you get a cute ruffled tankini top and matching mid-waist bottoms. The top features a loose, wire-free bodice and self-tie halter top for a comfortable fit that still keeps everything in place, making it popular among Amazon reviewers. One writes they only wish there were more colors available so they could buy multiple sets (you can choose from three solid colors and two patterns). To keep this suit looking its best, be sure to handwash and hang dry.

Sizes: S-XL

ReNew Plunge Triangle Top and High-Rise Hipster Bottoms

Thanks to Everlane's sustainable practices and supply chain transparency, we named it one of the best sustainable fashion brands. This Everlane triangle top and its matching high-rise hipster bottoms (sold separately) are made from 100% regenerated nylon fiber sourced from nylon waste like fishing nets, fabric scraps and industrial plastic (Everlane claims it has prevented 34,000 pounds of nylon waste from reaching the landfill). As for the fit, adjustable shoulder straps and a back-hook make this triangle bikini ideal for those who find it difficult to get their top to sit just so.

Sizes: XXS-XXL

Ribbed Bikini

This minimalist bandeau bikini top is simple yet provides ample coverage for smaller busts — plus the removable spaghetti straps make it easy to add more support if desired. One five-star review says this suit is a must-buy, noting that it "stayed in place all day without the straps" and "is lined, which is amazing."

Madewell's Second Wave line is made from 93% recycled nylon and 7% elastane, so you can feel comfortable and confident in this bandeau top and its matching cheeky bikini bottoms (sold separately).

Sizes: XXS-XXL

Compression Swim Bikini

Look like a cool surfer girl even if you haven't graduated from boogie boarding (we're right there with you). Good American's compression fabric is designed to mold to your body and hold everything in while you float around.

With a flattering swoop neckline and a front zipper that makes it easy to get the top on and off, you can pair the top with the brand's matching compression swim briefs, cheeky bottoms or swim shorts.

Sizes: XS-5XL

Ruffle Strap Underwire Bikini

From ruffled straps to a cinched neckline to unlined underwire cups, this swimsuit top incorporates all the best bathing suit trends in a subtle way that works.

Sold separately, we recommend pairing this top with the brand's V-front cheeky bottoms for a flattering fit. Both are available in burgundy (pictured) as well as a handful of other colors. Note that Abercrombie often has sales going on, so you may be able to grab a couple mix and match options while still sticking to your budget.

Criss-Cross Bikini Top

An intimates brand known for its cute triangle bralettes, Parade's line of swimwear is equally as popular. Case in point: The brand's best-selling criss-cross bikini top and matching thong bikini bottoms. While both feature minimal coverage, you'll feel secure thanks to adjustable straps and hook clasps. It's available in four different colors, including "snorkel," pictured here.

Sizes: XS-DD (top); XS-XL (bottom)

Yes, Kim Kardashian's loungewear, underwear and shapewear brand Skims now has a swimwear collection, and yes, we think it lives up to the hype. With options for every body type and coverage preference, we suggest the line's triangle top and dipped tie bottoms (sold separately) to anyone looking for a classic string bikini. It's uber-popular with hundreds of highly rated online reviews, with one saying they love it because it's the "perfect color, perfect fit, amazing material." Choose from five classic neutral hues or five limited-edition colors.

What to look for when shopping for a bathing suit

When shopping for a new swimsuit, here are a few things consider:

✔️ Style: First and foremost, you want to feel confident in your swimwear. No matter how trendy a suit looks on the hanger, if you don’t feel your best in it, it’s not the suit for you. Choose styles that you feel comfortable spending the day in. From one-pieces with or without sleeves, tankinis, strappy bikinis and sets that have a little more coverage, there is a wide range of styles to choose from.

✔️ Care: While some suits can be machine-washed, many styles are hand-wash only. Hand-washing your swimwear can extend its life, but machine-washing is more convenient and provides a better clean.

✔️ Versatility: A skimpy suit may be perfect for a day tanning or a weekend getaway with your friends, but it won’t work for beach sports. Consider what activities you will be doing while wearing your swimsuit. Some styles are designed for lounging while others are made for swimming laps; other options balance both with stylish details like thicker straps or zippers.

✔️ Padding: Like sport bras, swimsuit tops come in all different styles: underwire, built-in cups, removable cups or totally unlined. People with larger breasts tend to prefer cups, as they offer more support and lift. It comes down to personal preference when deciding which style is best. Just make sure to take out any removable cups when laundering to prevent them from getting twisted.

✔️ Return policy: As with any clothing purchase online, you'll want to pay attention to the brand's exchange policy, especially if you will be ordering a few sizes at once online to find the right fit. Some brands offer free returns while others may charge a fee. And when summer sales roll around, keep an extra close eye on how long the return time turnaround is.
